K-drama antagonists make every story even more interesting—we live for their crazy antics and revenge plans.
Especially if the evil male lead is also a sociopath it makes things even more interesting.
While most of them stress the hell out of us, there are those that are just plain horrifying.
We're talking about the evil male leads that have their own background music that just sends shivers down our spines.

He really doesn't care about anything or anyone as long as he gets what he wants.
At first, he appeared to be a bumbling lawyer from the Wusang firm company who had comedic traits and seemed to work closely with Hong Cha-young.
However, it was soon revealed that he is actually the de-facto leader and supreme chairman of the nefarious Babel Pharmaceuticals Group.
Furthermore, his real name is Han-Seok Jang, and that he is the true mastermind behind all the illicit activities that Babel Group had perpetrated in Korea.
He is also the older brother of Chairman Jang Han-Seo, who is externally known as the official chairman of Babel Group at the time.
2. Itaewon Class's Chairman Jang
